69958-53-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69958-53-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,5 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 69958-53:
(7*6)+(6*9)+(5*9)+(4*5)+(3*8)+(2*5)+(1*3)=198
198 % 10 = 8
So 69958-53-8 is a valid CAS Registry Number.
